Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): THIN-BEDDED LIMESTONE STRIKES NORTH AND DIPS SOUTHEAST AND IS INTERBEDDED WITH SHALES AND VOLCANICS. THE GRANODIORITE STOCK INTRUDES SEDIMENTARY ROCKS WEST OF THE MINE.
Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M242839, WHICH HAS BEEN DELETED.
Comment (Location): ON EAST FLANK OF TOBIN RANGE ON STEEP RIDGE NORTH OF MORNING VIEW CANYON. . INFO FROM LAND.ST :(1972); PREVIOUS QUAD DESIGNATION = BUFFALO SPRINGS 1:24000
Comment (Deposit): SCHEELITE OCCURS IN LENSES OF SILICIFIED LIMESTONE CUT BY NUMEROUS QUARTZ STRINGERS, 1-24 INCHES WIDE AND UP TO 50 FEET LONG. TWO LENSES YIELDED 1 TO 6 TONS OF SORTED HIGH GRADE ORE EACH AND TWO OTHERS YIELDED ABOUT 100 TONS ORE THAT CONTAINED ABOUT 2.5 % WO3. MINOR PYRITE AND MOLYBDENITE ARE ALSO PRESENT. JOHNSON AND BENSON REPORTED A 1 FOOT SAMPLE FROM NO. 1 ADIT ASSAYED 4.20% WO3 AND A 0.7 FOOT SAMPLE FROM NO. 2 ADIT ASSAYED 5.12% WO3.; MODEL NAME COULD ALSO BE: W VEINS.
Comment (Workings): 2 SHORT ADITS AND SEVERAL PITS.
Comment (Production): JOSON AND BENSON REPORT THAT 33 TONS OF SELECTED, SORTED ORE, CONTAINING 1.69-11.1% WO3 WERE SHIPPED (DATES UNSPECIFIED).
Comment (Development): BLOSSOM OPERATED THE MINE DURING 1941-1943 AND 1951-1954.
